I hadn't noticed that static functions were also present in the stubs, 
so I tried them but got the same results. I added a NSLog there as 
well, and got the same result:

+ (id) TestAuthentication:(CFTypeRef) in_parameters
{
    id result = NULL;
    TestAuthentication* _invocation = [[TestAuthentication alloc] 
init];
    [_invocation setParameters: in_parameters];
    result = [[_invocation resultValue] retain];
    NSLog(@"debug: isComplete: %d, isFault: %d, true: %d", 
[_invocation isComplete], [_invocation isFault], YES);
    [_invocation release];
    return result;
}

output: debug: isComplete: 1, isFault: 1, true: 1

To decouple this from the complex types, I wrote a little webservice 
in C# for MS-IIS called testInt that I've verified with SOAP Client 
from Scandalous Software that behaves correctly:

[WebMethod]
int testInt() {
  return 5;
}

that returns

<soap:Envelopexmlns:xsd=""xmlns:xsi="<A href="http://www.w3.org/2001/XMLSchema">http://www.w3.org/2001/XMLSchema
  instance"xmlns:soap="">
-<soap:Body>
-<testIntResponse xmlns="webservices.mydomain.com/myService">
-<testIntResult>-5</testIntResult>
</testIntResponse>
</soap:Body>
</soap:Envelope>

Again I added debug info to the code:
+ (id) testInt:(CFTypeRef) in_parameters
{
    id result = NULL;
    testInt* _invocation = [[testInt alloc] init];
    [_invocation setParameters: in_parameters];
    result = [[_invocation resultValue] retain];
   NSLog(@"debug: isComplete: %d, isFault: %d, true: %d", [_invocation 
isComplete], [_invocation isFault], YES);
    [_invocation release];
    return result;
}

and again it failed: debug: isComplete: 1, isFault: 1, true: 1

My call in this case was:
[Service1Service testInt:[[NSDictionary alloc] init]];

That is, an empty dictionary, so no parameters. I tried passing nil, 
but then it just crashed

For the authentication I called:
NSDictionary *serviceDict = (NSDictionary*) [myServiceService 
TestAuthentication:param];
NSLog(@"Entries: %d", [serviceDict count]);

and I got: "Entries: 0"

So either way isFault returns YES, and either way I get an empty 
NSDictionary back. Why is this, and how do I get it to return 
correctly? (you'd think it'd be easy enough calling an "int 
function()" ;-) )
